Scheduling data migration jobs in batch mode

Batch mode for data migration jobs is an mpx Manager GUI-only feature used to schedule multiple
jobs having the same priority, I/O size, and group options.
This option is particularly useful for migration jobs specified as Schedule for later and Serial Schedule
Jobs on the Data Migration Jobs Options dialog box, where the jobs need to be classified under a
specific group for better management.
DMS allows a maximum of 255 jobs to run simultaneously at any specific time per source array. To
optimize MPX200 performance, HP recommends that you run simultaneously no more than four jobs
on any specified source or destination array.
Consider a data center having multiple applications running on multiple storage arrays that need to
be consolidated, and data migration needs to be done on associated LUNs. The data migration
administrator must plan the data migration operation to minimize the application downtime. To achieve
this, the mpx Manager provides an option to create data migration job groups, as described in
"Creating a data migration job
You can combine all the source LUNs associated with a specific application into a single job group
and schedule it for migration using the Schedule in batch mode option. That way all the jobs can start
at a predefined time, which can be off-peak hours when the administrator can afford a small application
downtime.
Follow these steps to schedule a batch of data migration jobs:
1. Start the Data Migration wizard by following the steps specified in
Wizard" on page 45.
2. In the Migration Schedule Options dialog box, click Schedule in batch mode, and then click OK.

The left pane of the Create Data Migration Job dialog box shows a DataMigration Job (New)
option with icons for Source LUNs and Destination LUNs.
The right pane of the Create Data Migration Job dialog box shows the type of array (Source,
Destination, or Src+Dest) for each of the arrays available for configuring the data migration job.
3. Choose the appropriate source and destination LUN for the migration job by dragging and
dropping the LUNs from the right pane onto the Source LUN or Destination LUN under
DataMigration Job (New) in the left pane.
The mpx Manager populates the Source LUN and Destination LUN attributes and creates a new
DataMigration Job n (New) object below the first one. The default job name is created by using
the source and destination array names.
